Sorption Enhanced DiMethyl Ether Synthesis (SEDMES) is a promising option to overcome thermodynamic limitations of conventional DME production processes. In this work a 2D+1D heterogeneous dynamic model of the reaction/adsorption step in a tube of an externally cooled multitubular fixed bed SEDMES reactor is developed in order to investigate the...

Seasonal storage of heat in shallow aquifers for increasing the efficiency of geothermal energy systems requires a proper monitoring strategy. We expanded our earlier work on harmonic pulse testing (HPT) to incorporate the effect of a temperature front moving into the reservoir due to injection of hot (or cold) water. Our analytical solutions...

Two organosolv lignins extracted during pilot runs of the Fabiola process were analyzed, fractionated and chemically modified with ethylene carbonate (EC) to produce building blocks suitable for polymer synthesis. Isolation of low dispersity fractions relied on the partial solubility of the lignins in organic solvents. Lignins solubility was...

The Diels–Alder (DA) reaction of furans is a versatile tool in synthetic organic chemistry and in the production of sustainable building blocks and smart materials. Numerous experimental and theoretical investigations suggest that the diene scope is effectively limited to electron-rich furans, which excludes the most abundant and readily...

A large part of the population in many African countries lacks access to electricity, in contrast to the ambition of reaching universal energy access as expressed in the Sustainable Development Goals. Off-grid electricity technologies have been proposed as an important means to solve this challenge. It is uncertain, however, at what rate these...

Zonne-energie (hier bedoeld: zonnestroom) is een onmisbare bouwsteen voor een duurzaam en klimaatneutraal energiesysteem; wereldwijd, in Europa en in Nederland. De kosten zijn spectaculair gedaald door een zeer succesvolle combinatie van onderzoek & innovatie en opschaling door marktontwikkeling. Dat is goed nieuws voor de noodzakelijke...

Het doel van het project was om drie prototype badkamer renovatiepakketten te ontwikkelen en deze in zes huurwoningen te plaatsen voor het wat betreft warmtapwater aardgasloos of aardgasloos-ready maken van deze huurwoningen. In het hieraan voorafgaande TKI project MEED is een geïsoleerde gesloten douchecabine ontwikkeld met daarin geïntegreerd...

The importance of spatial resolution for energy modelling has increased in the last years. Incorporating more spatial resolution in energy models presents wide benefits, but it is not straightforward, as it might compromise their computational performance. This paper aims to provide a comprehensive review of spatial resolution in energy models,...

Using the example of how elite Nordic chefs use a relatively novel food such as seaweed in Nordic cuisine, we describe and develop a model of creative innovation in gastronomy services from a systems perspective. Seaweed has long had a connotation of poverty and austerity in the Nordic regions and had thus been a forgotten or marginalized food...

This report compares eleven OECD members in their status and expectation on flexible bioenergy. This includes Australia, Austria, Denmark, Finland, Germany, Ireland, Italy, Netherlands, Sweden, Switzerland and the United States of America. The actual role of bioenergy in the different countries strongly varies between sectors and countries, from...

A combined density functional theory and molecular dynamics approach is employed to study modifications of graphene at atomistic level for better H2 storage. The study reveals H2 desorption from hydrogenated defective graphene structure, V222, to be exothermic. H2 adsorption and desorption processes are found to be more reversible for V222 as...

Om de klimaatdoelstellingen voor Nederland in 2030 en 2050 te realiseren, zal offshore windenergie een belangrijk onderdeel van het energiesysteem moeten worden om zo de CO2 uitstoot te verminderen. Met de overheid en maatschappelijke organisaties heeft TNO de visie geponeerd dat in 2050 tussen50GW en 70GW aan offshore windenergie operationeel...

The synthesis of methanol from biomass-derived syngas can be challenging because of the high CO2 content in the bio-syngas, resulting in lower kinetics and higher catalyst deactivation. This work explores the in situ pre-treatment of a CO2-rich syngas with a CO2/CO ratio equal to 1.9 through the reverse-water gas shift reaction with the aim of...

Sailing in ice-infested waters has become more relevant for the Royal Netherlands Navy (RNLN). A method is developed to determine the technical safe speed for a single ice floe impact with a typical non-ice strengthened naval vessel. A representative ice floe impact load scenario is applied to three structural arrangements for the side shell...
